The recent charges (for example, in the letter “Group not suited for educational role in schools”, October 5) against the Society for Truth and Light over its contract from the Education and Manpower Bureau to train school teachers on human rights issues have amazed me.

There is no such thing as discrimination against a certain behaviour or act – discrimination can only be against a group of people. I believe the society has never had an agenda listing any group or individuals it will turn against. It only wants to discourage certain kinds of behaviour – gambling and anal intercourse below the age of 21.

Is having less gambling and this kind of intercourse in society equivalent to having a fox in a hen house? If letter-writer Peter Johnson is worried that public funds are spent on an organisation opposing homosexuality, then I must raise the point that funds from the Home Affairs Bureau have also been spent on the publications of a lesbian group. I suppose the government has been fair.

Mr Johnson accused the society of being intolerant and of claiming to have the monopoly on truth. But what is the point of his letter, apart from showing his own intolerance towards some people? Does he not also think that his letter claims a monopoly on truth?
